China, Chungking, January, 1933; France, Falaise (Leo Lesquereux 

 Coll.). 



The collection from Falaise, France, must have been made about a 

 hundred years ago, but the filaments and spores are in excellent condition. 

 This material is a part of a collection purchased from Leo Lesquereux by 

 the Philadelphia Academy of Sciences. Dr. Ruth Patrick identifies the hand- 

 writing on the label as that of Brebisson.
